Troubles Tripping Circuit Breakers With 10 Big 393 Motors?

This information and post would not be possible without the contributions on the Vex Forums made by James Pearman, a moentor on team 8888 in California.
Well we all thought it was great when we could use as many of the big 393 motors as we would like last year, but now we don’t have a choice and Vex no longer carries the smaller 269 motors. So what tends to happen is you run your robot too hard and the circuit breaker trips either in the motor of the Cortex stopping all activity for a period of time before it resets – sadness ensues.

Toss Up Strategies – Getting Over the Bump

We now have a field kit set up as Oscar Way so no more guessing!

One team, 5757 of Virginia, has been experimenting with a few drive designs that show how they react with the bump and showing them on You Tube. You can see all the videos here.

The 2013-2014 Vex Game – Toss Up

This year, the Vex game is called Toss Up. It looks like a lower scoring game with higher proportion of bonus derived from winning autonomous with 10 points to the winner. So get ready to program this year!

Toss Up has three equal and distinct zones each 4 foot by 12 foot long that defines the scoring zones. There are 24″ high plastic tubes on the far end from where you stand but before you get there you have to go under a 12″ bridge. And between the middle and close zones, you have a 2″ bump to navigate over! To make matters more challenging, there is a hanging bar this year – and it is…
